Lub capacitor yuav tsum tsis txhob muaj kev sib txuas ua ke zoo ib yam li cov xaim lossis cov resistor ua. Continuity implies ib txoj kev tsis tshua muaj zog rau
tam sim no ntws, thiab capacitors yog tsim los thaiv cov tam sim no ncaj qha (DC) tom qab lawv tau them. Nyob rau hauv qhov zoo tagnrho scenario, ib zaug ib
capacitor tau them tag nrho, nws yuav tsum ua raws li qhov qhib Circuit Court, txhais tau tias yuav tsum tsis muaj kev txuas ntxiv ntawm nws cov terminals.
Txawm li cas los xij, thaum lub sijhawm them nyiaj lossis thaum kuaj nrog ohmmeter, lub capacitor yuav luv luv qhia qhov tsis kam lossis
txuas ntxiv. Qhov no yog vim hais tias lub capacitor yog them, thiab thaum lub sij hawm lub sij hawm no lub xeev, cov kuj yog qis dua. Raws li lub capacitor
tsub nqi, qhov kev tiv thaiv yuav tsum nce, thiab lub ohmmeter nyeem yuav tsum mus txog infinity, qhia tias lub capacitor yog
ua raws li qhov qhib Circuit Court.
Hauv cov ntsiab lus:
Initial Low Resistance (Transient State): Thaum lub capacitor pib txuas nrog lub voj voog lossis kuaj nrog ohmmeter, nws tuaj yeem
luv luv qhia tsis tshua muaj zog raws li nws tsub nqi.
Stable High Resistance (Charged State): Thaum lub capacitor tau them tag nrho, nws yuav tsum muaj kev ua haujlwm siab, thiab lub ohmmeter
kev nyeem ntawv yuav tsum mus txog infinity, qhia tias nws ua raws li qhov qhib Circuit Court.
Tsis muaj kev txuas ntxiv: Hauv lub xeev ruaj khov, lub capacitor yuav tsum tsis txhob muab txuas ntxiv zoo li cov xaim. Nws yuav tsum thaiv DC tam sim no.
Nws yog ib qho tseem ceeb kom tso tawm lub capacitor tag nrho ua ntej kuaj nrog ohmmeter kom tsis txhob muaj hluav taws xob poob siab. Tsis tas li ntawd, thaum
kuaj cov capacitors, nws yog feem ntau qhia ntau dua los siv cov khoom siv ntsuas capacitor lossis multimeter nrog capacitance
kev ntsuas muaj peev xwm, raws li cov cuab yeej no tuaj yeem muab cov ntaub ntawv muaj feem cuam tshuam txog lub capacitor txoj kev noj qab haus huv, xws li nws
Capacitance tus nqi thiab sib npaug series kuj (ESR).
